In some working environments, the temperature change range is large. The thermal expansion coefficients of different materials are different, and the materials of the suction nozzle and the suction disc may expand or shrink to different degrees due to temperature change, so that gaps or stress are generated at the connecting parts, the plug-in type suction nozzle is not tightly matched, and then the suction nozzle is caused to fall off. At the same time, the vacuum chuck will vibrate during work. If the vibration frequency and amplitude of the equipment are large, and effective damping measures are not taken, the small suction nozzle is easy to gradually loosen and even fall off in this frequent vibration environment.

At the same time, after the suction nozzle falls off, the components being sucked may fall off. If the components fall off at the non-designated position on the circuit board, the normal patch process will be disturbed, and the components or the circuit board may be damaged.
